MOUNT FOR PRINTERS AND LIKE BLOCKS.

Specification of Letters Patent.

I atented Dec. ML, IHvIo.

Application filed October 6, 1913. Serial No. 793,577.

To all whom it may concern:

Be it known that I, PERCY RoY BLACK- MORE, subject of the King of Great Britain and Ireland, residing at 126 Empress avonue, Ilford, in the county of Essex, England, compositor, have invented new and useful Improvements in Mounts for Print ers and like Blocks, of which the following is a specification.

My invention relates to improvements in mounts or mounting boards for process line and like blocks, stereos or the like of the type comprising compound 'wood and metal blocks.

The objects of my invention are to provide a simple and rigid backing for the printing or like surfaces which will not warp or buckle which shall be more durable than the present wooden backing now used and in which the marginal flange or beard now necessary to pin the printing surface to its backing, may be eliminated when required.

Suitable arrangements may be made to secure the inclosing material to the insertion and pins or nails having suitable heads are secured on the various surfaces of the insertion so that their heads project the required distance and act as chaplets to support and position the insertion in the casting box, so that when the stereo. or other metal or alloy is poured therein, the insertion will be totally inclosed by a reinforcing case, which also acts to insulate it from the action of atmospheric and like changes.

The printing surface may be attached to the prepared mount in the usual manner or when it is desired to eliminate the marginal flange orbeard it may be attached by casting or sweating one of the stereo or other metal plates or layers, thereto, either prior to or during the preparation of the mount. After the printing surface is attached the whole block is trimmed to gage in the usual manner.

In order that my invention may be more readily understood reference is had to the accompanying drawings in which Figures 1 and 2 are two vertical sectlons at right angles of a block in which the insertion is totally incased by the stereo or other metal or alloy, and Fig. 3 is a section showing a method of casting the stereo or other metal or alloy around the insertlon.

Referring now to the drawings a prepared piece of block of insertion D of a size slightly less than that of the printing surface to be mounted has a complete shell or casing around it so as to be totally surrounded or covered thereby. The block of inser tion D has suitable holes, channels, ducts, apertures, recesses or the like d cut or otherwise formed therein to allow the stereo or other metal or allo to engage them and thereby key the case H to the insertion D The printing surface A may either be secured to the case H in the process of casting the latter around the insertion D in which case the marginal flange or beard may be eliminated, or it may be secured by nails, pins, tacks or the like passed through a marginal flange or beard into the mount in the usual way.

The method of casting the casing H around the insertion D is shown in Fig. 8 in which the printing surface A is tinned or fluxed on its back and laid face downward in a casting box.

Pins, nails or the like J having suitable heads j are secured at intervals over the block of insertion D so that the heads project above the surface thereof to an extent about equal to the thickness of the casing H required. Type high gages K are brought against the side pins J and the cover L of the casting box closed down so as to press upon the top ones so as to hold the block in position while the stereo or other metal is poured.

What I claim as my invention and desire to secure by Letters Patent is In a mount for printers blocks a single piece of insertion one side of which is not greatly less in area than the mount, pins having projecting heads distributed over the larger surfaces of the piece of insertion, through holes in the insertion, an enveloping case of metal cast around and completely enveloping said insertion on all its faces and connecting strips of metal between the larger surfaces of the enveloping casing through the holes in the insertion to prcvent bul ing of the top and bottom faces of the enveloping case.

In witness whereof I have hereunto set my hand in the presence of two witnesses.

PERCY ROY BLACKMORE.
